Lack of food security in southern Bhutan in particular has been attributed to climatic conditions there that make it difficult to successfully store grains and cereals for any length of time, as well as to pests consuming stored grains.
En particular, la falta de seguridad alimentaria en Bhután meridional se ha atribuido tanto a las condiciones climáticas, que dificultan el satisfactorio almacenamiento de los granos y cereales durante cierto tiempo, como a las plagas que consumen los granos almacenados.
